ACCOUNT-FILE.

ooaass.

To all whom it 'may'concern:

Be it known that I, WILSON BARR, Jr., of the city of Hamilton, in theProvince of Ontario, Canada, have invented certain new and usefulImprovements in Account-Files, of which the following is aspecification.

This invention relates to files in which account slips are filed onstiff leaves suitably supported so that any given leaf is immediatelyaccessible. In designing such a file I have had two main objects in view(1) it is desirable that each leaf when being used shall occupy exactlythe same position as any other leaf when said other leaf is in use; (2)there must be no sliding movement of one leaf or another which tends todislodge or spoil the accounts. The usual objects of cheapness anddurability of construction and reliability of action are of course alsosought.

This present invention relates to a modification of the inventiondescribed in my copending application, No. 512,853 and the particularobject I have in view is the securing of substantially the same resultsby means differing in detail from those shown in said co-pendingapplication.

I attain my objects by the constructions hereinafter particularlydescribed and illustrated in the accompanying drawings, in which Figure1 is a perspective view of my improved account file. Fig. 2 is avertical section of the same. Fig. 3 is a plan view partly in section.Fig. 4 is a vertical section of part of the device, showing how a bunchof leaves may be turned from vertical to horizontal position.

In the drawings like letters of reference indicate corresponding partsin the different figures.

A is the casing, preferably of L-shape, as shown.

B are a series of account filing leaves which are of ordinaryconstruction and are provided with the account holding clips C. Theseleaves are pivotally connected at their lower or rearward edges by meansof the hinges a, so that one or more of said leaves may occupy either asubstantially vertical or a substantially horizontal position. I aimparticularly in the present invention to so arrange the apparatus thatwhen any leaf occupies the position at the front of the vertical leavesor at the top of the horizontal Specification of Letters Patent.

leaves that it will occupy substantially the same position as any of theother leaves under like circumstances. I accomplish this by arranging itso that the leaves, when in a vertical position, are restrictedsubstantially to a backward or forward movement and when horizontal arerestricted substantially to a vertical movement, the guiding means beingso arranged that one or more of the leaves may be turned freely from thever tical to the horizontal position, or vice versa.

To guide the leaves when vertical, 1 provide the pair of tracks D which,though approximately horizontal, will usually incline somewhat towardthe rear to give the leaves a slight rearward inclination. The tracks Dare engaged by the projections E, which are preferably rollers journaledon the last leaf F. This last leaf may be a complete leaf but ispreferably only a half leaf being used more particularly as a followerfor the rest of the leaves. The leaves when in their horizontal positionare guided by the substantially vertical tracks G and H. The tracks Gare located adjacent the forward ends of the tracks D while the tracks Hare located toward the forward part of the casing A. Between thesetracks G and H a table I is movable, being normally vertically springpressed as hereinafter described and provided with projections L,preferably rollers engaging the forward sides of the tracks G.Theoretically this table may be considered as the first leaf.

It will be noted that the vertical pressure of the table tends to pushup the front vertical leaf. This tendency is restrained by the use ofthe pair of tracks J which are engaged by the upper edges of the. leavesB. These edges are preferably provided with the rollers b to reducefriction. The first leaf K is also preferably hinged to the table by ahinge 6 thus restraining the bunch of leaves when all are vertical frombackward or forward movement in a horizontal direction, as well asrestraining the horizontal leaves from backward movement. The tracks Hare preferably adapted to be en gaged by the rollers 72 to restrain theleaves from forward movement in a horizontal direction. From thisconstruction it follows that though the leaves are accurately guidedwhen in either the horizontal or vertical positions, yet the corners ofthe leaves will freely pass the edges of the tracks D and G when a bunchof leaves is being turned from the horizontal to the vertical position,as indicated in Fig. 4.

There exists a tendency for the last leaf F to tilt backward when theremaining leaves have been drawn down to a horizontal position. Iobviate this trouble by providing a pair of toggle levers M having widebearings on the back of the casing and on the last leaf or follower F.These absolutely prevent any tilting of the last leaf and indeed in asmall cabinet may render the use of tracks D unnecessary. While anysuitable means may be provided for yieldingly supporting the table I,yet I prefer the mechanism shown. A pair of bent levers N are journaledon the sides of the casing and are connected by the cross bar C. A. coilspring 0 connected to one end of this lever and to the casing pressesthe cross bar up against the under side of the table. A second pair ofbent levers P are pivoted on the sides of the casing and are connectedby a cross bar cl engaging the under side of the table I at the oppositeend to the cross bar 0. These bent levers P are connected with the bentlevers N by means of the links Q whereby they move together and impart asimilar movement to each of the cross bars 0 and d.

From this construction it follows that as each leaf is turned down froma vertical to a horizontal position the table is depressed the thicknessof one leaf, the next vertical leaf going forward to the positionformerly occupied by the leaf just turned down. It follows then thatwhen either side of a leaf is exposed the exposed side occupies the sameposition as the similarly exposed side of every other leaf in the file.When all the leaves are in the vertical position they may be withdrawnfrom the file by disconnect ing the last leaf from the toggles F, and bdisconnecting the hinges e of the first leaf from the table. It will benoted that at no time is any rubbing movement of one leaf on the otherin any way possible.

What I claim as-my invention is 1. In an account file the combination ofa plurality of account holding leaves pivotally connected at their loweredges whereby one or more of the said leaves may occupy either asubstantially vertical or a substantially horizontal position;substantially horizontal guide tracks; projections on the last leafriding on said tracks; a second pair of tracks substantially parallel toand distant from the first with the under side of which the upper edgeof each leaf may engage; apair of substantially vertical tracks;projections vertically movable with the first leaf adapted to engage theforward sides of the vertical tracks and yielding means tending to pressthe leaves upward when they are in the substantially horizontalposition.

2. In an account file the combination of a plurality of account holdingleaves pivotally connected at their lower edges whereby one or more ofsaid leaves may occupy either a substantially vertical or asubstantially horizontal position; substantially horizontal guidetracks; projections on the last leaf riding on said tracks; a secondpair of tracks substantially parallel to and distant from the first withthe under side of which the upper edge of each leaf may engage; a pairof substantially vertical tracks; projections vertically movable withthe first leaf adapted to engage the forward sides of the verticaltracks; a second pair of vertical tracks substantially parallel to anddistant from the first vertical tracks and with the rearward side ofwhich the outer edges of the leaves may engage when horizontal; andyielding means tending to press the leaves upward when they are in thesubstantially horizontal position.

3. In an account file the combination of I a plurality of accountholding leaves pivotally connected at their lower edges whereby one ormore of said leaves may occupy either a substantially vertical or asubstantially horizontal position; a pair of substantially horizontaltoggle levers each pivoted at one end on a stationary part and at theother on the last leaf; guiding means tending to restrict the leaves toa substantially vertical movement only when they are horizontal; andyielding means tending to press the leaves upward when they are in thesubstantially horizontal position, the guiding means being adapted topermit of the leaves being swung from the vertical position to thehorizontal, and vice versa.

This 31st day of August 1910.
